During the 2010 election, the Conservatives polled 18% of vote in Scotland but gained less than 2% of the seats. Without a fairer distribution of the votes in Scotland, the Conservatives will never be able to gain their fair Scottish representation.
Here is some Scottish Election data from the last two general Elections, 2005, 2010. Spot the (several sets of) unfairness:
Below, is the result table from 2010 General Election for Scotland. Again, spot the unfairness.
Notice the massive unfair seat allocation. Particularly see the benefit to Labour and the grossly unfair penalisation of the Conservatives. In 2010, Lib-Dems actually got roughly the correct vote/seat ratio. If you divvied up the seats according to vote share Labour should have got 24 -25 seats, each of the other parties should then have got about 11 seats each
In Scotland, using the First Past the Post voting system, the Conservatives (and the SNP) are punished in exactly the same way that other minority parties are punished across the the UK. The people of Scotland end up with an unrepresentative grouping at Westminster, which strongly leans away from what a sizeable voting minority wish for, leaving these minorities with reduced representation, or as with the Conservatives, with trivial representation.
Scotland may not be a Tory heartland under any voting system, but under First Past the Post the Conservatives are guaranteed an insignificant representation.
There used to be a phrase used to define those Conservative who rejected the old class base system. A phrase used to define Conservatives who sought to promote the best interests of the whole of the UK. They used to be called One Nation Tories.
So how can these "One Nation Tories" today still support First Past The Post, especially when it harms their cause so badly as shown above?
By supporting FPTP the Conservative simply entrench themselves in their English heartland and so fail to be a One Nation party. Conservative party supporters need to look to the long term, not just the petty gains to be made in the short term by staying with an outdated and unfair voting system.
Vote for AV on Thursday.
